Modalities — Cursor Wins

Modalities: Cursor compared with QuillBot
Feature	Cursor	QuillBot
Text Input	Yes. Agent chat is driven by text prompts in the input. You type instructions, attach @ context, and switch models from that same field.	Yes, requires free plan. Paraphraser and grammar tools take typed text. Directory lists Freemium. Homepage was Cloudflare-blocked this round.
Image Upload / Vision	Yes. You can drag an image into chat or paste a screenshot. Agent also reads image files (.png, .jpg, .gif, .webp, .svg) for vision-capable models.	No. Writing assistant, not vision.
Image Generation	Yes. Agent can generate images from text or reference images for UI mockups and diagrams. Files land in the project assets/ folder and show inline in chat.	No. Does not generate images.
Voice Mode	Partial. A microphone in the chat input dictation-transcribes prompts, and iOS can dictate to agents. That is one-way voice input, not a two-way spoken conversation loop.	No. Not a voice assistant.
Video Understanding	Partial. Grok Bot accepts video attachments (up to 200 MB) so that Bot can inspect recorded footage. Core Agent chat is documented for images and files, not a general YouTube/video-watch loop, so this is not product-wide video understanding.	No. Not a video product.
Video Generation	No. Not a video generation product.	Unknown. Cloudflare blocked the public site; video generation was not confirmed.
File Upload (PDF, DOCX)	Yes. Chat @-mentions attach files and folders. Grok Bot also takes PDFs, Office docs, CSV, JSON, source, and notebooks as message attachments.	Unknown. A document uploader was not confirmed (Cloudflare).
Code Execution	Yes. Agent runs shell commands in the terminal, watches output, and can execute tests, linters, and builds as part of a task.	No. Not a code sandbox.
Audio Input	Partial. Grok Bot message attachments include audio files (25 MB each) in the same table as documents and images, so pre-recorded audio can be sent for a task. Core Agent chat is not documented as a general audio-file transcribe surface, so this is Grok Bot only.	No. Not a speech product.
Canvas / Artifact Editor	Yes. The Agents Window is an agent-first workspace beside the classic IDE editor, with diffs, file search, and split layouts. Agent also opens in a Cmd+I sidepane.	No. Text editor, not a canvas.
Screen Sharing / Computer Use	Yes. Cloud Agents run a full desktop and can drive mouse/keyboard plus the browser (computer use). You can take over the remote desktop, then hand control back to the agent.	No. No computer-use.

Memory & Context — Cursor Wins

Memory & Context: Cursor compared with QuillBot
Feature	Cursor	QuillBot
Persistent Memory	Partial. Grok Bots retain facts and summaries across work. Core Agent chat relies on Rules instead of auto-memory between completions, so this is not ChatGPT-style global memory.	No. Not a chat-memory product.
Large Context Window	Yes. Each chat has a fixed model context window with a usage ring. Cloud Agents let you pick context size; several models document up to 1M-token extended context.	Unknown. Word limits were not fetched this round.
Custom Instructions	Yes. Project and user Rules (.cursor/rules plus User Rules) inject persistent instructions into Agent. Always Apply, glob, and @-mention rules are documented.	Unknown. Modes (standard/fluency) exist in market; not re-verified this round.
Conversation History	Yes. Past chats persist so you can @Chats into a new prompt. CLI resume/continue reloads prior threads; iOS keeps an agent inbox of running conversations.	Unknown. Not confirmed this round.

Integrations — Cursor Wins

Integrations: Cursor compared with QuillBot
Feature	Cursor	QuillBot
Web Search / Browsing	Yes. Agent has a Web tool that generates search queries and performs live web searches during a task.	No. Not a search engine.
Plugins / Extensions	Yes. Cursor Marketplace installs official plugins that bundle rules, skills, MCP servers, and hooks. Teams can ship a private marketplace; VS Code extensions still work in the editor.	Unknown. Integrations were not confirmed this round.
API Access	Yes. Cloud Agents API, TypeScript/Python SDKs, Admin API, Analytics API, and related endpoints are documented. They run agent workflows, not a raw chat-completions API.	Unknown. Not confirmed this round.
Zapier Integration	Unknown. No first-party Cursor Zapier app was listed on cursor.com/docs. Automations document GitHub, GitLab, Slack, Linear, and webhooks instead.	Unknown. Not checked.
Custom GPTs / Bots	Yes. Grok Bots are named durable agents with a profile, skills, routines, and shareable templates. You create, duplicate, and share a Bot the way Custom GPTs are specialized agents.	No. No custom-GPT store.
Real-time Collaboration	Partial. You can share a Cloud Agent URL with teammates (read-only unless team follow-ups are on). Grok Bot group chats exist. This is not a simultaneous multiplayer editor session.	No. Not a multiplayer doc.
Live Social Data Integration		No. No live social firehose.
Live Citation Mapping		Unknown. A citation generator is part of the product in market; it was not verified this round.

Developer — Cursor Wins

Developer: Cursor compared with QuillBot
Feature	Cursor	QuillBot
Function Calling	Yes. Cursor connects to MCP servers that expose tools the model can execute. Agents call those functions from chat and Plan Mode, with user approval before each tool run by default.	No. Not a developer tools API.
Streaming Responses	Yes. iOS follows agent work live and watches the chat stream as the agent codes. The TypeScript SDK iterates streams; ACP clients handle streaming session updates.	Unknown. Not confirmed.
Fine-Tuning	No. Public APIs run hosted agent workflows. Docs do not offer a customer fine-tune SKU for foundation weights; you pick Cursor and third-party hosted models.	No. You do not train QuillBot.
Embeddings API	No. Cursor APIs are agent, admin, and analytics endpoints, not a vector embeddings API for converting text into embeddings in your own app.	No. Not an embeddings API.
Structured Output (JSON)	Unknown. ACP and SDKs exchange JSON-RPC/tool payloads, but no first-party JSON-schema guarantee for model replies was documented on the API overview.	No. Returns rewritten text, not JSON schema.
Reasoning / Thinking Mode	Yes. The model catalog lists Thinking variants and GPT reasoning-effort options (for example gpt-5-high). The SDK exposes thinking messages and a reasoning-effort parameter.	No. Paraphraser, not Deep Think.
Local Execution		No. Cloud web app.
Open Weights		No. Closed product.
Multi-Agent Orchestration		No. Not an orchestrator.
